The two figures below show 3D views of respectively atan2(y, x) and arctan( y / x ) over a region of the plane. Note that for atan2(y, x), rays in the X/Y-plane emanating from the origin have constant values, but for arctan( y / x ) lines in the X/Y-plane passing through the origin have constant
[1] [2] All functions use floating-point numbers in one manner or another. Different C standards provide different, albeit backwards-compatible, sets of functions. Most of these functions are also available in the C++ standard library, though in different headers (the C headers are included as well, but only as a deprecated compatibility feature).
In engineering problems, especially in the area of solar energy application, the solar azimuth angle, which can be computed from the x- and y-component of the vector pointing to the Sun using the atan2 function, normally measures from due North (positive y-axis) or due South (negative y-axis), this can be achieved by using atan2(x, y) or atan2 ...
Atan may refer to: Mathematics. arctangent (atan), a trigonometric function atan2, the two-argument function implementing the arctangent in many computer languages;

5. Borden American Cheese Singles. The truth is, so many of these cheeses taste identical. Borden and Harris Teeter are really similar, both lacking any distinct flavors that make them unique or ...
The advantage of atan2 over atan is more that atan2 has an expanded range, from −π to π. However, that isn't relevant here since the arguments are always positive.) Regarding the "stone age" nature of this formula, you should pause to consider the fact that spheres are used for other things in mathematics besides approximating planets.
